Description
Technical field
The utility model belongs to food packaging applications, and in particular to one kind three layers of composite plastic sheet thermoformed articles of printing
Processing unit (plant).
Background technology
Plastic sheet can pass through hot briquetting processing and thermoformed articles, including blow-molded article or Blister product is made.
A kind of composite plastic sheet is disclosed in Application No. CN200610123422.3 Chinese invention patent application
The production method of thermoformed articles.As shown in Fig. 1, its main technical schemes includes several steps：First, it is thin in transparent plastic
Printing forms pattern on film, and the figuratum plastic sheeting of printing is compound on plastic sheet；Then, in the drive of servomotor
Lower mobile composite plastic sheet 1 is heated and softened to heating post by heater 2 to plastic sheet 1；Then, exist
In the presence of servomotor, plastic sheet 1 is moved again to shaping post, by producing the mould 3 of malleation or negative pressure
The position heated and softened on composite plastic sheet 1 forms concaveconvex structure；Finally, whole product is completed by last handling process
Production process.
But in the production process of reality, it is found that above-mentioned production method has following point：First, to composite plastic
The heating and softening of media sheet, forming process are two independent post processes, and not only production efficiency is low, and composite plastics sheet
During being moved to shaping post after the local heating softening of material, composite plastic sheet is easily locally deformed with, and this is just
The molding effect of composite plastic sheet can be influenceed；Second, the composite plastic sheet obtained by the above method is double-layer structure, this
The concaveconvex structure of kind of composite plastic sheet be for containing food, and a face of plastic sheet can directly with food phase mutual connection
Touch, and the harmful substance to human body is easily discharged in plastic sheet.
In view of the problem of processing unit (plant) of existing composite plastic sheet thermoformed articles is present, need badly provide it is a kind of new
The processing unit (plant) of three layers of composite plastic sheet thermoformed articles, to overcome above mentioned problem.
Utility model content
